What is The epidermis of a herbaceous stem has small openings called that allow gas exchange between the tissues inside the stem and the atmosphere?
The epidermis of a herbaceous stem has small openings called stomata which allow for gas exchange between the internal tissues of the stem and the atmosphere. Stomata open to facilitate the uptake of carbon dioxide for photosynthesis and the release of oxygen and water vapor. They also regulate the loss of water through transpiration.
What are the special structures in the cell membrane that allow water and sugar pass through it made of?
These special structures are called protein gates or protein channels. Water is able to diffuse through the cell membrane since it is a small molecule. However, there are channels called aquaporins that allow water to enter the cell. A glucose molecule cannot just diffuse into a cell. There are glucose channels on the surface of the cell membrane that bind glucose molecules and allow them to enter the cell.
What allow water to enter the seed?
Water enters the seed through a process called imbibition, where the seed absorbs water through its seed coat. This triggers metabolic processes in the seed that allow it to germinate and start growing. The water penetrates the seed through small pores or cracks in the seed coat.
What is the whole between two guard cells in a leaf called?
It's called a stoma (plural stomata) and its function is to allow carbon dioxide to enter the leaf for photosynthesis. The guard cells sre responsible for regulating the size of the stoma.
What are openings in a leaf called?
Openings in a leaf are called stomata. Stomata are small pores located primarily on the underside of a leaf that allow for gas exchange, such as the intake of carbon dioxide and the release of oxygen and water vapor.
Does madreporite allow water both inside and outside the body?
Yes, madreporite is a small, porous structure in echinoderms that allows water to enter the water vascular system in order to facilitate movement and other functions. It does not allow water to pass through to the outside of the body.
Why do objects absorb water?
Objects absorb water through a process called osmosis, where water molecules move from an area of high concentration (outside the object) to an area of low concentration (inside the object). This happens because many materials have small gaps or pores that allow water to pass through. Once inside the object, water can be trapped within the material's structure, causing it to become saturated.
The ability of water to rise in small openings?
This ability is called capillary action, which occurs due to the cohesive and adhesive properties of water molecules. These properties allow water to be drawn up into small spaces, such as in plant roots or in a thin tube.
What is the solution of flood?
Making gutters to allow the water to flow inside it.
Is every item inside the world made with water?
no. to keep it simple all items in the world are made of small particles called atoms.

Stomata open to facilitate the uptake of carbon dioxide for photosynthesis and the release of oxygen and water vapor. They also regulate the loss of water through transpiration.
What is the small opening in a seed is called?
A miniature plant inside the seed is called an embryo

What are small particles that don't allow water to absorb quickly?
Chloroplast
What is a meniscus used for?
the meniscus is not actually used for any thing water has certain properties that cause it to kind of climb up the sides of things it is inside of the meniscus is what this small amount of water is called
What is the name of the process of the ability of water to pass through a rock?
The process is called permeability, which refers to the ability of water to flow through the small spaces within a rock or soil. Permeable rocks allow water to move through them easily, while impermeable rocks do not allow water to pass through.
What are the breathing pores in a stem called?
The breathing pores in a stem are called stomata. They are small openings that allow for gas exchange, including the intake of carbon dioxide and the release of oxygen and water vapor.
